and the first few chambers were visited by James Burton in 1822, but the
tomb was later buried by flood debris and backdirt from excavations
nearby. It was not until 1995, when
Theban Mapping Project (by
Kent
Weeks) relocated the tomb's entrance and explored its interior, that
the tomb was found to be the largest ever found in the valley. So far,
150 chambers have been located, but the symmetrical plan of the tomb and
the likelihood of more doorways if many walls mean that it is likely to
contain at least 200 chambers.
